Virtopsy Research Group, University of Bern/Switzerland
To prove that a suspect assaulted the victim by biting her arm, investigators first created a digitized 3-D model of the wound using photogrammetric measurements (high-resolution photos taken from multiple angles) and a 3-D surface scan . Then they made a cast of the suspect’s teeth, and digitized that as well . Aided by the computer, investigators fit teeth to wound . The result: a perfect match.
